WL#3170: NDB: Dynamic BINLOG_FORMAT change

PROBLEM
It is with the current implementation not possible to change
binlog format dynamically when using NDB. (The current
implementation is described in WL#2712.)
SOLUTION
<To be discussed>
Note:
Discussion between Lars Thalmann and Guilhem Bichot, 2006-03-01:
Lars --
WL#2712 is a little bit different though. It is not possible to
switch when using NDB. I think we should close this WL anyway and
instead create a new one for making it possible to switch also for
NDB.
Guilhem --
I made it impossible when using NDB, because Tomas said NDB wasn't
ready for on-the-fly changing.
